WITNESS S ROBERT J. GIVENS, OF ENTERPRISE, IDAHO.

PROTECTOR FOR THE TIMERS OF EXPLOSIVE-ENGINES.

Application filed March 17, 1917.

T 0 all whom it may concern Be it known that I, Ronnn'r J. GIVENS, a citizen of the United States, residing Enterprise, in the county of Owyhee and State of Idaho, have invented new and useful Improvements in Protectors for the Timers of Explosive-Engines, of which the following is a specification.

This invention relates to protectors for the timers of explosive engines and the object is to provide a casing of flexible material which shall inclose the end portions of the separate wires connected with the timing mechanism, and which shall also inclose the outer removable cap of the timer proper and prevent injury to the several parts by reason of the entry of foreign substances of any character, or injury to the insulation by excessive heat developed by the engine.

In the accompanying drawing, forming part of this specificationz- Figure 1 is a perspective view showing the casing in operative position.

Fig. 2 is a view of the casing detached.

Fig. 3 is a detail showing certain features of the construction of the casing.

Fig. 4 i a transverse section through the protecting covering, and showing in section the cap of the timer to be protected.

In describing the invention, I do not deem it necessary to refer to th construction of the timer but have merely indicated the outer removable cap of this timing mechanism by the number 10 and the arm thereof adapted to have connection with the operating rod by means of 12. The several terminals are designated respectively 14, 15, 16 and 17 and the wires leading thereto by 18, 19, 20 and 21. These wires are usually scparated from one another for a distance of several inches and are then inclosed in an outer insulating cover 22.

The casing may be formed of leather and comprises an rilarged end portion 25 and a neck portion 26, the former inclosing the cap of the timer and the latter inclosing the separated portions of the wires connected with the terminals. The enlarged portion 25 of the casing is apertured at 27 for the accommodation of the central boss 28 of the cap 10 and is also apertured for the arm 12 above referred to and for the oiling device 30 between the boss and said arm. A further aperture 31 is provided at the extreme end of the neck portion for the accommodation of a wire leading to the headlight.

Specification of Letters Patent.

Patented Feb. 12, 1918.

Serial No. 155,589.

The portion 25 of the casing is made to conform to the cone-shaped surface of the timer, and a line of stitching shown at'33 connects adjacent sides of a transverse cut in the canvas or leather. The outer edges of portion 25 extend just beyond the several terminals and have connection with the edges of a ring-shaped member 36 also of leather which extends inwardly toward the sides of the cap 10, and said inner edges are provided with cars which are turned back in the manner illustrated to provide means for securing a tension cord 87 passing between the ears and the adjacent surface of ring 36. This ring is also of flexible material and is connected to the aforesaid outer edges of the member 25 by stitching shown at 39.

A series of apertures is provided along the edges of the neck portion 26, these apertures being shown at 40 and apertures 41 are also provided in the meeting edges of ring member 86, these meeting'edges being in Substantial alinement with the apertured edges of the neck portion when said neck portion is rolled to position to inclose the wires leading to the timer. A single lacing may be provided for connecting all of these meeting edges and securing the casing in position.

Among the advantages of the device mention may be made of the fact that the separate wires are brought together and not only protected from injury of all kinds, but facilitate the removal of the cap, since there are no separate wires to come into engagement with tools or projecting parts and cause entanglement. The protecting device is also of service in preventing the leakage of current and the breaking of the wires at the terminals through any cause.

I claim 1. In a device of the class described, a casing for a timing device comprising a cover having an enlarged portion adapted to inclose the timer proper and the terminals thereof, a neck portion connected with the casing, and means for securing the device in position.

2. In a device of the class described, a

' covering for a timing device including a casing formed from a sheet of flexible material and having an enlarged portion, and a neck portion projecting therefrom, an annular member adapted to surround the timer and secured to the outer edges of said enlarged portion, means for producing tension at the inner edges of the annular member, and means for connecting the edges of the neck portion.

In a device of the class described, a protecting covering for a timer and the wires thereof comprising a sheet of flexible material havin a neck portion, means for securing the neck portion around the Wires, an enlargcd portion connected with the neck portion and adapted to cover the outer cap of the timer anc the terminals thereof, a ringlike member surrounding the cap of the timer and having connection with the outer adjacent edges or the enlarged portion, said ring-like member being adapted to be disposed on e side of the terminals of the timer opposite to the side covered by the aforesaid enlarged portion, and tension means for securing the meeting edges of the covering.

4-. In a device of the class described, a covering; for a timing device, including a casing formed from a sheet of flexible material and having an enlarged portion and a neck portion projecting therefrom, an annular member adapted to surround the timer and secured to the outer edges of said enlarged portion, and means on the annular member for securing the covering in position.

In testimony whereof I atlix my signature.
